Description
The OPB702 family consists of an infrared emitting diode and a choice of NPN silicon phototransistor (OPB702), photodarlington (OPB702D), or base-emitter resistor for low light suppresion (OPB702R). The IR LED and phototransistor are mounted side-by-side on converging optical axes, in a black plastic housing.

Features
• Focused for maximum sensitivity
• Phototransistor (OPB702) or Photodarlington (OPB702D) or Phototransistor with base-emitter resistor (OPB702R)
• Low cost plastic housing
